We look at the division of 826866 by 78 
We want to figure out the number of times 826866 can be divided by 78.

Advancing to step 1:
If we divide 8 by 78, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 78

On to step 2:
78 goes into 82 1 times with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 78 from 82 to get 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 78

Step 3:
78 can be fit into 46 0 times, resulting in a remainder of 46.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 46, we get 46.
Include the next digit (8) from the dividend after 46, then repeat: 468 / 78

Going ahead to step 4:
If we divide 468 by 78, we get 6 and a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 106.0
Subtracting 468 from 468 leaves us with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 78

On to step 5:
78 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 1060.0
If we take 0 away from 6, we end up with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 78

Advancing to step 6:
If we divide 66 by 78, we get 0 and a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 10600.0
If we subtract 0 from 66, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 7:
If we divide 660 by 78, we get 8 and a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 10600.8
If we subtract 624 from 660, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 8:
78 goes into 360 4 times with a remainder of 48.
The next digit of our result is 4. 
Result so far: 10600.84
Subtracting 312 from 360 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
If we divide 480 by 78, we get 6 and a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 10600.846
The remainder is 12 after subtracting 468 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
The number 78 fits into 120 1 times, leaving a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 10600.8461
Deduct 78 from 120 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 11:
The number 78 fits into 420 5 times, leaving a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 10600.84615
Subtracting 390 from 420 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 12:
If we divide 300 by 78, we get 3 and a remainder of 66.
Record the quotient 3 as the next digit in the result. 
Result so far: 10600.846153
The remainder is 66 after subtracting 234 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 13:
78 can be fit into 660 8 times, resulting in a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 10600.8461538
The remainder is 36 after subtracting 624 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 14:
360 divided by 78 is 4 with a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 10600.84615384
Subtracting 312 from 360 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 10600.84615384 and a remainder of 4.8e-08.
